PTB330 Digital Barometer was also installed, for measuring atmospheric pressure in ANSA

Data: 21 February 2022

This time we are introducing the PTB330 Digital Barometer, which is a sensor for measuring atmospheric pressure, a very important meteorological parameter for landing and take-offs at the airports and an integral part of our Automatic Weather Monitoring System – New AWOS and Automatic Weather Monitoring System – AWOS Upgrade supplied from the American company DTN and that will have a special role in setting up provision of aeronautical meteorological services.

The Vaisala PTB330 digital barometer is designed to read the proper barometric pressure readings in the most challenging conditions. Built around Vaisala’s trademarked BAROCAP® sensor technology, the PTB330 combines absolute pressure measurement and exceptional accuracy with low hysteresis and long-term stability.

Both systems: the new AWOS and the AWOS Upgrade, pose each 2 of the barometers of the PTB330, on RWY17 and RWY35, each barometer has 3 measuring caps, which means that along the runway, we will have 12 barometric measurements of atmospheric pressure.

PTB330 is used in aviation to determine the atmospheric pressure values ​​of QNH and QFE. The QNH represents the pressure reduced to sea level, based on the altitude and temperature of the observation site. The QFE represents the height-corrected pressure of small differences in altitude, for example, the air pressure at the airfield elevation.
